This read-create value, in seconds and ranging from 1 to 10, sets the timeout for the trace-route request. An admin tunes it to control how long the switch waits for a response at each hop before declaring that probe failed, and it cannot be changed while a test is already 'inProgress'. For example, leaving this at its default of 5 seconds is usually sufficient on a healthy fabric, but an admin might raise it on a congested or long-haul fabric.
